Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in PHP allow remote attackers to inject |
| 19 |
arbitrary HTTP headers, perform cross site scripting or in some cases |
| 20 |
execute arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
PHP is a general-purpose scripting language widely used to develop |
| 26 |
web-based applications. It can run on a web server with the mod_php |
| 27 |
module or the CGI version and also stand-alone in a CLI. |
| 28 |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Stefan Esser of the Hardened PHP project has reported a few |
| 44 |
vulnerabilities found in PHP: |
| 45 |
|
| 46 |
* Input passed to the session ID in the session extension isn't |
| 47 |
properly sanitised before being returned to the user via a |
| 48 |
"Set-Cookie" HTTP header, which can contain arbitrary injected data. |
| 49 |
|
| 50 |
* A format string error while processing error messages using the |
| 51 |
mysqli extension in version 5.1 and above. |
| 52 |
|
| 53 |
Impact |
| 54 |
====== |
| 55 |
|
| 56 |
By sending a specially crafted request, a remote attacker can exploit |
| 57 |
this vulnerability to inject arbitrary HTTP headers, which will be |
| 58 |
included in the response sent to the user. The format string |
| 59 |
vulnerability may be exploited to execute arbitrary code. |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
There is no known workaround at this time. |
| 65 |
|
| 66 |
Resolution |
| 67 |
========== |
| 68 |
|
| 69 |
All PHP 5.x users should upgrade to the latest version: |
| 70 |
|
| 71 |
# emerge --sync |
| 72 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.2" |
| 73 |
|
| 74 |
All PHP 4.x users should upgrade to the latest version: |
| 75 |
|
| 76 |
# emerge --sync |
| 77 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-4.4.2" |
| 78 |
